One idea is a vehicle-miles traveled tax, which would track driver habits via GPS and charge per mile driven....Another is to charge some sort of congestion fee on overclogged highways....Mica, for his part, has suggested extending the Build America Bonds program....A bipartisan team affiliated with the Carnegie Endowment has proposed an upstream tax on oil combined with a variable gas tax that shrinks when oil prices rise and expands when oil prices plummet.

Uh huh. Or we could, you know, just raise the gas tax. We are ruled by idiots.
